Control of Volunteer Sethoxydim-Resistant Corn (Zea mays) in Soybean (Glycine max)

摘要

Research was conducted in 1995 and 1996 to determine the potential for commonly used volunteer corn herbicides to control volunteer sethoxydim-resistant (SR) corn in soybean. Greenhouse studies showed that the SR corn hybrid tolerated 181 times more sethoxydim than the susceptible sister hybrid. SR corn also tolerated other acetyl CoA carboxylase (ACCase) inhibitors including fluazifop-P, quizalofop-P, and clethodim with 30×, 27×, and 7× magnitudes of tolerance, respec- tively, compared with the susceptible hybrid.
